1到1的反向关系“belongsTo”给出了一个集合laravel而不是model

Question

In my Profile model I setted this relationship

    public function lease()
{
    return $this->belongsTo(Lease::class, 'lease_id', 'id');
}

And in my Lease model I seeted this way

public function profile()
{
    return $this->hasOne(Profile::class, 'lease_id', id);
}

As longs as I know in laravel you could do

$profile = factory(App\Profile::class)->create();

$profile->lease()->get();

And then responds correctly with the model inside of a collection And if I do $profile->lease Responds correctly directly with the model

It isn't supposed that dynamic propertis execute the query right away like a shortcut of ->lease()->get()? Why it gives different formatted results?

Answer 1

When you are calling get on a builder you are getting a collection always. When you call first on a builder like that you will get a model or null. The dynamic property for the relationship, based upon the relationship object, will either query with get or first respectively when it loads it. Which is why $model->relationship is returning you the result you expect.

The relationships that are singular, cause a find and the ones that are many cause a get.
